water jacket and rudder

[jmr12]

Traxxas spartan 3 years old. Stock..what size water jacket do I buy? Looking at getting an aluminum one from Kintec racing. Also, I want to put on a dual H2O pick up rudder. Will I need a defferent conecting rod from the servo to the new rudder?
Thanks.

It's 36mm can and 50-60mm long. Just look for a rudder that is direct bolt on with out mods, ose do one and I assume kintec would not need any mods. If you run dual intake I would run dual outlet, I just bought another stock spartan outlet

I just installed Kintec's aluminum water jacket on my Spartan and it works great and fits tight on the motor to eliminate the leaking. I also installed Kintec's dual pickup rudder and the install was easy. The factory steering link works fine. The only mod that has to be done is drilling new holes through the hull. This is not difficult but care must be taken to ensure that the rudder is perfectly plumb with respect to the boat. Definitely need dual outlets with the dual pickup's. I bought some stainless outlets from Kintec and put them both in opposite corners of the hull and filled in where the stock outlet went for a cleaner, more symmetrical look.
